Draw the network. $($You may use MSP or draw an AOA or AON network by hand.$)$

Using Excel$,$ calculate the expected time $($TE$)$ and variance for each activity.

Using the expected times, find the path with the longest expected time. What is the expected time to complete this path? $($Use the analytic method.$)$

Find the probability that the critical path will be completed in $38$ days or le
